NITED STATES PATENT Giirrcnc C. WrSTAFFORD, OF SAYBROOK, CONNECTICUT.

IMPRCVED PAVEMENT.

Specication forming part of Letters Patent No. 66,Q01, dated June 25,1867; antedated Maich 27', 1867.

To all whom it may concern:

Be it known that I, C. W. STAFFORD, of Saybrook, in the county ofMiddlesex and State of Connecticut, have invented a new and usefulImprovement in Pavements; and I do hereby declare the following to be afull and exact description ot' the same, reference being had to theaccompanying drawings, which are made part ot' this specication, and inwhich- Figure l is a view in perspective of a section of my pavement,showing band and keys. Fig. 2 is a plan view of a row of blocks, takenfrom one end ot' a section of my pavement and laid upon their sides,showing longitudinal arrangement of keys. Fig. 3 is a partial sideelevation of a section of my pavement as it would appear it' a portionof the outer part thereofwere removed.

This invention consists of a pavement composed of wooden blocks set onend, in sections, the blocks in each section being held together by aniron band and cross-keys.

A represents blocks of any desired size, and of any suitable wood,parallelopipedous in shape, so cut that the ends running tra-nsverselyot' the grain of the wood are oblong, except in the cases of the blocksat the extremities of alternate rows, the ends of which are square, inorder that all the blocks may break joints. A suitable number of theseblocks are placed together, so as to form a section, as shown in Fig. l,and are held together in the section by an iron band, B, passing roundthe outside thereof, in a recess made in the outer blocks for thatpurpose, the band not being equal in width to the depth of the recess,in order that it may not prevent contiguous sections from being placedin close contact. Wooden cross-keys C run transversely through thesection in similar recesses, the function of the cross-keys being toprevent displacement of the blocks from upward or downward pressure. Aconvenient number of the sections thus constructed, placed in contact ona suitable foundation, t'orm a pavement.

Each block, before it is placed in lits section, is coated with hotcoal-tar, and after the sections are formed, the cracks between theblocks are Iilled with sand dried in a furnace. The sections are thusthoroughly prepared before they are put down, and a pavement maytherefore be made ot' them with great rapidity.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. I claim the constructing of sections ot' pavement composed ofmetallic bands, grooved blocks of Wood, and keys, substantially as andfor the purpose set forth and described.

2. I claim a pavement made up of sections of wooden blocks,substantially as described, for the purpose specified.

The above specification of my invention signed by me this 20th day ofMarch, 1867.
